At the tail end of his whispering, Robin trails off, his eyes catching and following the cowering creature... Though his flickering smirk grows steady as he continues hanging, his arms slack and his tone close to mocking.

"Oh, look. You've gone and scared him, Vincent."

Lifting his head just the slightest amount, his expression turns to surprise. "No, I..." The rest of his sentence gets caught, he wrestles with something, a lot quieter now, "But I can't just..."

Whatever it is he can't do, it doesn't seem to matter much--because his shoulders slowly sink, and Robin gets lowered to the floor along with them.

Vincent finally talks awkwardly at Phalanx, raising a hand uselessly, "Hey, I'm sorry, don't--"

Robin, possessing far more people skills, simply rolls his own shoulders and crawls back onto the bed, following until he can put an arm calmly around Phalanx's shoulders.

"It's okay, friend. He's not actually mad."

(Even if a tense sigh from Vincent might suggest otherwise.)
